Study Finds Each Persons Gut Microbiome Reacts Differently To Foods
The human body has up to 4.5 pounds of microbes in the gut, known as the gut microbiome. Two-thirds of the gut microbiome is unique to each individual, and composition is dependent on the food we eat, the air we breathe, and other environmental factors. A new study suggests that the bacteria in each persons gut respond differently to foods, even when they have similar nutritional content.
Participants in the study included 34 healthy adults. The researchers took daily stool samples over the course of 17 days. They also documented participants’ nutritent intake. Two participants were assigned to only consume meal replacement beverages in order to assess the effect of a stable diet.
The researchers found that gut microbiome composition was more strongly associated with food choices rather than conventional nutrient profiles. They also found that daily microbial responses to diet were highly personalized, even when participants consumed the same foods.
In addition, they found that consuming a stable diet (meal replacement beverages), did not produce microbiome stability. Instead, overall dietary diversity was more strongly associated with microbiome stability.
The study was conducted by researchers from the University of Minnesota. It was published on June 12, 2019 in the journal Cell Host and Microbe.
